range
It shows the drive status during the pump control operation according to the following table:
Status Description
REGL Drive is regulating in PID mode.
PMAN The drive is at protected manual mode.
OMAN Drive is in manual mode, not protective mode.
HIPP
Drive is stopped (pause) due to high pressure, according to
the read data in the analogue input.
HIPR
A fault due to high pressure has occurred according to the
read data in the analogue input or in the digital input.
FLOD
The drive has stopped (Pause status) due to No Flow
detection.
NFLO The drive has tripped (Fault status) due to No Flow detection.
CAVS The drive has stopped (Pause status) due to Cavitation.
CAVI The drive has tripped (Fault status) due to Cavitation.
LOPR The drive has tripped due to low pressure fault.
LOWA
The drive has tripped due to a fault detected in one of the
digital inputs configured as „No Water‟
CYCL The drive has tripped due to excessive starting cycles.
IRFA
The drive has tripped due to a fault in the irrigation equipment
which has been detected in the digital input configured in that
option.
FLOW The drive is limiting the speed to limit the flow.
OFF The drive has received the stop command.
SLEP The drive is in sleep mode because there is no flow demand.
BYPA
The drive is forcing the speed after starting or stopping some
of the fixed pumps.
RAMP Setpoint ramp activated.
FILL
The drive is running at reduced speed because Pipe Fill
function is active.
COMP
The time of automatic stop has expired and the drive is
stopped.
JOCK The Jockey pump is running.
PRIM Priming pump is connected.
FINP Fault occurred because the pressure switch is open.
Additionally, the reference in PID mode (as %) followed by feedback (as %) is shown.

The status of the fixed pumps 1-3 is shown according to the next information:
Status Description
OFF Pump disabled by keypad.
RDY Pump ready to start.
ON Pump started.
FLT
Pump in a fault status (input which controls the signal is
active).
Note: See digital input configuration in Pump Control mode.
G1.7 and G4.1.4 parameters are linked to this.

It shows the present value read by the analogue input or by pulse input where sensor is
connected.
